SPECIFICATION forming part of Letters Patent N 0. 665,844, dated. January 8, 1901. Application filed February 1, 1900. Serial. No. 3.578. (No model.)

To (all whom it nut concern.-

lle it known that LFRANK \V. WEEKS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Machines for Manufacturing Carbon-Coated Paper, of which the following is a specification.

The principal object of "the invention is to to provide a simple, economical, and eflicient machine for manufacturing carbon -coat ed paper.

A further object of the invention is to pro vide a simple, economical, and efficient machine with mechanism for applying asurface of carbon to a sheet of paper and to harden, finish, and polish the same.

The invention consists in the features, 'combinaiions, and details of construction hereinafter described and claimed.

In the art to which this invention relates it is well known that the ordinary carbon or manifold paper of commerce as usually man u factu'red made by supplying the carbon to the paper in liquid form and by the aid of a brush. The resultant article is a paper having a supply of carbon thereon in a loose or soft condition which during the process of manufactaring has permeated the paper to such an extent as to discolor the opposite side and render it unfitforall purposes excepting that of making manifold copies or reproductions. A further objection to the usual article is that in, handling, the paper the carbon or coloring-matter comes off, so as to soil the fingers as well as to discolor adjacent sheets of paper with which it may come in contact. This old type of paper is generally used in 80. what is known as the interleafing system of manifolding-that is, Where carbon-sheets are interposed between two or more leaves of paper, so as to provide copies of the origi nal imprint or impression. This method of using the paper is expensive, in that it requires considerable time to interleai' the sheets of carbon, and in cases where a large number of entries have to be made on dilferent sheets of paper it occupies considerable time.

It has long been the desire of manufacturers and users of manifolding or carbon paper to produce by machinery or otherwise a paper provided with a surface of carbon or coloring material which has been fixed, hardened, and polished th; son in such a way as to enable the paper to be printed onone side and-the user to handle or come in contact with the same without soiling the person of zoo .tinte is saved, the work of making a large per as it iear s the roll in ataut ondition--- surface of carbon, and thereby remove the r of these levers is provided with a bolt C, p v

the user or the paper and other materials l with which such paper might oomein contact.

To accomplish this result has heretofore been deemed impossible, and a vast amount of lahor and time, entailing a great financial ontin tryintr to accomplish the result-namely,

the production of paper with a hardened and finished carbon-nurface and hitherto without success.

The article prod need by the improved prom estor method and the machine herein de scribed are espeeially advantageous to L116 arts, in that. iailroad, express, telegraph, a id large wholesale companies may have their paper prepared so that one side may be eat-honcoated and the other printed in blank, no as to use it for the purpose of making; rerot'dH, dupli ates, and triplicates thereof at a minimum expense, thus saving: immense tiles without the use of interleating-shtnits.

objections incident to the paper now in general 11530.

In constrmsting a machine in noeordanoe with nly improvements 1 provide a frame pot tion A of the desired size, shape, and strength to support the operative and other int-chauisms in their desired position. This frame portion, as shown in tho dravtings, ronsista of two standards secured together by means of the tio-rod n and Figs. 5 and ti, extending transversely from one standard to the other, and at. its upper portion with a bed B, upon hitsh the paper travels, as will he more fully hereinafter described.

'l o support a. roll of paper which it is de eirahlo to mirhonaeoat, one end of the machine is provided with a. shaft 1. upon which the rollof paperr' is wound, and slit-h shaft is removahly secured in position by means of the pins o and (9*, Figs. i and 4', one of which, is passed directly across the journal part of the shaft (see Fig 4;) and the other across the boxes 1-. it. is desirable to keep the pa in other words, to apply a hraiuto the shaft. or some portion thereof, so that, when the operative nnwhauisln is stopped the roll wilt not continuiits rotations. To accomplish this result, one end of the machine is provided with a flanged hraltdwhoel (1", Figs. 3 and i, the tread portion of which in engaged by two shoes and r 'l-hese shoes are pin-- otaliy secured to two oseillatinglevers (Fami C pivoted to the frame at. c and resembling somewhat an ice-tongs. The free end of. no

oied thereto and having its free end passed through a perforation in the other swinging lover. The end of the bolt is threaded and provided with a hand-sorew het'ween which and the perforated lever is inserted a spring 6. The arrangement of parts is sneh (see Fig. 2) that by turning the hand-wh el one way or the other the shoes are pressed with leased therefrom, so that the operator can ,eontrol, as seems desirahle, the rotation of {the roll of paper.

To apply a surface of eat-hon to the paper, (see Fi i. 5,) the paper is brought" up over an idler-roll and over the upper surface of the lied and in Contact. therewith. Arranged adjaeent to the front end of the machine is a carhon-supt'ilyingr roll 1), formed of a central shaft, a wood drum, and an outer covering, of felt Wound around the same. One pol" tion of this roll is in contact with a mom of carhon E or other coloring mart-rial, more fully hereinafter desrrihed, and another portion of the surface of the roll is in contact with the paper. It is desirable to arrange the journal portion of this carhowsnppl'ying roll in adjustable bearingmso that it can he pressed against the paper with the desired amount of friction. In order to aeeomplish this result, the shaft of the carbon-enpplying roli has its journal portions rotatahly mounted in boxes (I, Fig. L, at or near each end thereof, which in turn are held in position upon the primary slides D', Figs. 2,17, 18, and 19,) and the slide is provided with a. l'iin zet'l eap J, pivoted thereto in such a manner that it may be thrown hack to remove the hex or swung into closed position, as shown in Fig. 1!), to confine the liUX. This hinged cover is slotted at its free end, so that it may he clamped by a thnmh-nut and hell. r1 It is also desirable to provide means by which these boxes may he raised independently and simultaneously. In order to accomplish this result, each of the slides has a projecting split lug :2 extending outwardly therefrom, as shown in Fig. 17, in Whioh is inserted a. not. 1/, threaded 0n the inside and outside. Inserted into the threaded axial opening of this not is an adjustingserew (1. the upper end of which is provided with a hand wheel d and a bevel-gear ii The lower end of this adj usting-serew has its heariiig rotatably mounted in a lug, d and is pre vented from having endwise movement by means of a collar (1 and the look-nuts (1 It will be readily seen from an examination of Fig. 17 that as the hant'l-wheel is turned in one direetion or the other the slide l) is moved upwardly or downwardly, carrying with it the end of the color-supplying roll away from or towardihe paper to be carboneoated.

Both slides are provided with adjusting mechanism, as shown in Figs. 7 and 17, and in'order, therefore, to transmit power and greaterforeo against the ln'ake-wheel or re-.

motion from the single hand-wheel to bpt'h of I the adjusting-screws a cross-shaft D is provided and mounted in bearings d at or near each end thereof. Each end of this crossshaft is provided with a bevel-pinion 0P en gaging with the bev'el-pinions on the upper ends of the adjusting-screws, as shown clearly in Fig. 7, so that the hand-wheel is turned in either direction it imparts a simultaneous and similar rotation to each of the adjustingscrews. Independentadjnstmentoftheslidcs is obtained by turning the sleeve-nuts d in either direction.

The coloring material in this kind of a machine is preferably made of a composition of carbon or other desirable coloringmatter mixed with wax and tallow, made in the shape of a cake, and of the consistency of hard soap, and which may be conveniently termed practically-hard carbon but owing toirregnlaritiesin density and distribution of the material fol-min the color-cake the color-supplying roll usually takes up more material than is necessary or takes it in patches, and this in spite of the fact that feeding mechanism, hereinafter described, minimizes this objection. In order to get rid of this surplus and distribute the material evenly over the color supplying roll, an evening-roll F, Figs. 5 and 7, is provided and rotatably mounted in suitable bearingsfat each end thereof, so that it may contact the color-supply roll throughout its length. lhese bearings are adjustably held in position on the threaded sleeves f, which sleeves are arranged upon studsf having threaded ends engaging the caps of the slides l), Figs. 2 and 17. A detail view of a similar structure to this sleeve and'stud is shown in a stud and sleeve on the left upper portion of Fig. 13 and will be more fully hereinafter described. From the foregoing it will be seen that either or both ends of this evening-roll can be raised or lowered whenever desirable onnecessary, so as to remove as much or as little of the surplus coloring material from the color-supply roll as mayseem desirable or necessary.

Color having been supplied to the paper by means of the color-supplying roll I), it is left in a more or less imperfect conditi0n-that is, the carbon is practically in a soft condition on the paper, and it becomes necessary to permanently affix the coating of carbon to the surface of the paper and harden and finish the same. In order to accomplish this result, a pair of rubbing-rolls G and G, Figs.

- and 5, are provided and arranged in suitable bearings, so that they rotate with their lower surfaces in contact with the carboncoated surface of the paper. It is desirable that these rolls, the outer surfaces of which are preferably formed of felt'or like material, be given a reciprocating motion longitudinally of the rolls or transversely of the ma chine across the face of the paper, as well as a rotary motion, which will not only serve to more effectually distribute the carbon on the paper and rub it into the same, but breaks up any tendency toward making lines or giving the surface of the carbon 3. grain-like appearance. In order to reciprocate the rubbingrolls, one end of each of the shafts is provided with a grooved collar g and 9, adapted to be engaged by yokcs 91*, secured to a vibrating platen 9 (See Figs. 2 and 3.) This platen 1s secured to a rock-shaft G having a crank g at its lower end, the pin of which engages with a grooved cam g mounted upon one end of a rotating shaft g. (See Fgs. 2 and 4.) It is desirable that each of these rubbing-rolls have an independent adjustment by which it may be lowered toward or raised away from the carbon surface of the paper, so as to provide the necessary friction for rubbing the carbon into the paper. In order to accomplish this result, the journals of the shaft are mounted in bearings G at or near each end of the stem, and these bearings in turn are mounted upon threaded sleeves, which also in turn are rotatably mounted upon studs 9 screw-threaded .into a frame portion H, Figs. 1 and 2, which is slidingly mounted, as hereinafter descni bed, upon each side of the main frame oilt'he machine. A detail view of a structure exactly similar to this adjustable serew-sleeve is shown in a similar sleeve and stud at the upper left-hand side of Fig. 13, which will be more fully hereinafter described when considering that figure.

After the carbon or coloring material has been rubbed in, as above described, it is desirable to clean the surface of the paper, and for this purpose two cleaning-rolls I and I are provided and rotatably mounted in suitablebearings, so that their surfaces will contact the colored surface of the paper and clean off the surplus amount of material which re mains after the ru bbing-rolls have done their work. These cleaningrolls are composed of steel central shafts 2, which furnish the journal therefor and support pine drums 2." thereon, Figs. 5 and 6. These wooden d ums are provided with an outer surface of mohair plush'and preferably should be about five inches in diameter. The cleaning rolls or journals thereof are mounted in bearings 1 upon threaded adjustable sleeves I similar in their construction to the adjustable sleeves hereinbefore described and as shown in Fig. 13, by which the rolls may be moved toward or from the surface of the paper whenever desirable or necessary. The studs of these sleeves are also mounted on the sliding frame above deseri bed.

When the operation of cleaning the carboncoated surface of the paper has been accomplished, it is desirable to polish the surface of the same, and in order-to do this a pair of polishing-rolls K and K are preferably provided. These polishing-rolls (see Figs. 6 and 14) are formed of rotatable shafts and pine drums carrying a multiplicity of wing portions It, let into the cylindrical surface of the drum and, held in place in any desired manner, preferably by the strips of metal These wing portions are formed of felt or similar material, which as the rolls are rotated rapidly remove any surplus material on the paper and give a polish unto the hardened surface thereof. The shafts of these rolls are mounted in adjustable bearings K which in tupn are mounted upon the adjusting screwthreaded sleeves it These sleeves are mounted upon studs (see Fig. 13,) let into the sliding frame II, so that the sleeves may be turned in either direction to raise and lower the adjustable bearings.

It will be appreciated that the strip of paper should be drawn over or fed across the bed of the machine and against the direction of rotation of the color-supply, rubbing, cleaning, and finishing rolls. A careful examination of the above description and drawings will show that it is far preferable to draw the paper across the same from one end of the bed of the machine, for the reason that color-supplying, rubbing, cleaning, and finishing rolls will then act to spread and evenly distribute the carbon on the paper rather than simply rolling, over the carbon, which act would not so evenly distribute and iinish the carbon. In order to accomplish this result-the feeding of the paper along the bed of the machine in an economical and eflicient mannerapper and lower feed-rolls L and L, Figs. 2 and 6, are provided. These feed-rolls are formed of a central steel shaft 1 and drums of suitable material. The lower shaft has its journals rotatably mounted in the bed of the machine, while the upper shaft isjournaled in boxes I, slidingly mounted in standards (see F5". 2,) so that it may be raised and lowered whenever desirable or necessary. The raising and lowering of the upper roll are accomplished by means of a screw L having a hand-wheel 1 the lower end of the screw engaging with the sliding box and the threaded portion of the screw, as shown in Figs. 2 and o. engaging with a cross-bar of the standard.

It is desirable, and in fact necessary, that both the journals of the upper feed-roll be raised and lowered at the same time. In order to accomplish this result, the adjustingscrews are provided with beveled pinions l9, relatively slidingly mounted upon the screws and engaging with similar beveled pinions I, see Fig. 3,) mounted upon a cross-shaft l particularly shown in Fig. 3,) so that as the handwheel L upon one of the adjustingscrews is rotated both of the adj listing-screws are rotated in a similar direction and serve to raise and lower both ends of the feed-rolls simultaneously.

The lower feed roll is provided with a driven gear L mounted on one end of its shaft, (see Fig. 1,) engaging with a pinionl which is connected to a driving-pulley L arranged to be driven from the main drivingshaft.) The driving-gear L meshes with the gear L on the upper feed-roll, so as to opcrate ordrtve the same. The other and of the lower feednoll (see Fi". 2) is provided with a spur-gear L", arranged to engage with a train of gearsdiereinafter described,and operate the ni'echanisrn for cutting the paper into sheets.

hen the carbon-coated. surface of the paper has been polished, itis practically finished and it can, ifdesi red, be brought into engagement with the second drum (not shown) and rolled around thereon, upon which it may be kept for such future use as may be desirable or necessary. In the present instance, however, it is preferable to cut the strip of carbon into sheets of the desired size, and in order to accomplish this result one end of the bed of the machine is provided with a ledger or cutter oar-M, adapted to be contacted by a rotating cutter N, mounted upon a shaft N, by which it is rotated. (See Fig. 6.) This shaft is given its rotation by means of a spur-gear N*, which in turn is operated by means ofintcrinediatcgears nand n, Figs. 2 and 3, which mesh with and are operated by the gear L on the lower feed-roll. These intermediate gears are mounted upon a swinging arm 0, which has a segmental groove 0 therein, through which a clamping bolt and not 0 is passed. From this constrnction it will be seen that the rotating cutter can be thrown into and out of action whenever desirable or necessary and also that the size of the gear on the lower feedroll can be changed to regulate the length at which the sheet of paper will be out. For instance, if it is desired to cut the longest sheet possible, then the smallest gear that it is possible to put on the lower feed-roll should be placed thereon. When it is desirable to cut as short a sheet as possible, then the largest gear that can be placed on the lower feedroll should be placed thereon, so as to operate or rotate the cutter-bar as rapidly as possible.

\Vhen the strip of paper has been cut into the desired lengths, as shown in Fig. 6, the sheets fall into a jog-box P, from which they may be removed whenever desirable or necessary.

There are times in the operation of a machine of this class when it is necessary to raise all of the rolls-such as the colonsupplying, rubbing, cleaning, and polishing rolls from contact with the carbon surface of the paper. This, if possible, should be done at one and the same time or during the same operation. In order to accomplish this result, the rubbing, cleaning, and polishing rolls have their adjustable sleeves mounted upon the sliding frame H, above referred to. This sliding frame, which is formed of two sliding brackets, one on each side of the main frame, is held in position by shouldered guides h, Figs. 13 and 14, which pass through elongated perforations h therein. These guides, as suggested, are made in the form of elongatcd-shoulder-pieces resembling caps, which are secured to the main frame of this machine by means of capscrews k (See Fig. 13.) [Two rock-shafts H and H (see Figs. 5

[O the same time that the frame of the and lowered, which as fact with machine in any through those nuts and samples,

and 6) are provided, having eccentric vpins 71, Figs. 13 and 14, extending outwardly from each end thereof and engaging elongated openings h in the sliding frame, so that as 5 the rock-shafts are vibrated the sliding frame is raised or lowered.

- The means provided for raising and lowering the color-supplying rol'l from and into contact with the paper to be carbon-coated, at the rubbing and other rolls are raised or lowered in e slide D, (shown in Figs. 17, l8, l9, and O.) is slidingly mounted in a secondary or saddle slide R, which in turn is slidingly mounted on machine. The lower end of this saddle is provided with a slot 'r, en gaged by an eccentric-pin r, extending out from a rock-shaft B, Fig. 5, so that as this rock-shaft is vibrated the saddle R is raised a consequence raises and lowers the color-supplying roll. To vibrate all these rock-shafts H, H and R at the same time, an operating-lever S is provided and vibratingly mounted upon a rock- ;5 shaft 8.

The other end of this rock-shaft s (seeFigs. 5 and 7) is provided with a lever S, conliected, by means of the links 8', s ,and 8 Figs. 5 and 6, with level-arms 8 upon each tirtonall of the rock-shafts, which raises and lowers the slides and sliding frame, thus va sing and lowering all of the operating-rolls, color-supplying rolls, the, from and into conthe paper to be operated upon. The color-supplying material isrnade, as above stated, in the shape of a brick and of abtjut the consistency of hard soap. Means should he provided by which it can be automatically fed to the color-supply roll in the desit'ed amount and at the desired rate of speed.

In order to accomplish this result,a color-holding frame or box is provided, havingits' base '1, Figs. 1 and 2, secured to the bed of the desired way, preferably by means of the cap-screws i, (see Fig. 10,) by which it is held in fixed position. It will be readily seen, however, that the loosening of these cap-screws will permit of the frame being moved inwardly or outwardly, as may be ilesirable or necessary. This carbon-suppo'rting frame has an upwardly-extending flange 'l" at its rear edge, through which two feed-screws 15 are passed and in which they .are rotaiably mounted, the frontend of which frame is'also provided with two lugs i, one at each side thereof, in which the ends of the feed-screws are supported and also rotatably mounted. A follower-bar T is slidingly mounted on the bed of the color-box and grooved, (see Fig. 8,) so that guides i may be inserted therein. The outer ends of the follower are slotted, and in these slots are loosely inserted nutst, prevented from rotating by having, pins i engaging with holes in the follower. 'lhe feed-screws are passed are in threaded on- -which in gagement therewith, so that as the. feedscrews are turned in one directi n or the other the follower-plate is moved forwardly or backwardly either to force the cake E of coloring material toward the color-supply roll or permit a fresh cake to be inserted therein. A removable cap portion U, Figs. 1: and 22, is held by thumb-screws u in engagement with the color or carbon box to prevent the easy withdrawal bf thecake of coloring material and also its being raised out of the box do ring the rotation of the color-supplying roll.

To operate the feed-screws, across-shaft V is provided, having worms '0 (see Fig. 9) engaging with the worm-gears v on the outer ends of the feed-screws. One end of the cross-shaft is provided with a beveled gear V, which is meshed with a bevel-pinion 0 Figs. 2 and'3. This bevel-pinion is mounted upon anintermediate shaft V which isjournaled in fixed bearings 11 and v (See Figs. 2 and 16.) The opposite end of this intermediate shaft V is provided with a frictionwheel V engaging with the face of a friction-' disk V, so that as the friction-disk is rotated the intermediate shaft V is also rotated, turn rotates the bevel-pinion v and gear V, the cross-shaft, and by means of intermediate mechanism the feed-screws.

It is desirable to vary the feed of the cake of coloring material to suitdiit'erent circumstances and conditions, and in order to accomplish this result the friction-wheel above referred tois rotatably mounted upon a sleeve o Fig. 16, which in turn is slidingly mounted upon the intermediate shaft. This sleeve has a nut portion '0, extending outward there from and adapted to be engaged by an adjusting-screw V so that as the adjusting-screw is rotated in the one direction or the other the friction-wheel is moved toward or away from the center of the friction-disk, which necessarily increases or decreases the speed of the intermediate rotatable sl1aft,and thereby the speed at which the cake of coloring material is fed toward the color-supply roll.

There are times when it may be desirable to feed one end of the cake of coloring material toward thecolor-supplying rolland permit the other to remain stationary, 'to arrest the feeding movemeniof the cake of coloring material, or to move the follower backwardly and insert a fresh cake without stopping the machine. In order to accomplish this resuit, (see Figs. 22, 23, and 24,) the wormgears above referred to are loosely moufi'ted upon the ends of the feed-screws. Disks or plates V are secured to the end of the feedscrews adjacent to the worm-gears, the faces of both of which are in direct contact, These plates are provided with holdingspins V"', the ends of which are adapted to engage with indentations r in the face of the worm-gears. Helical springs v serve to hold these pins in engagement with the indentations, so that as the gears are rotated the feed-so rows are likcwise rotated. These holding-pins are provided with transverse pins 1), passed through irregular perforations 0 in the plates, so that as the holdin pins are drawn backwardly they may be a so turned a step into the laterally-extending portion of the irregular slot 1" to hold them out of engagement with the worm-gears and permit the engagement of such gears without a consequent rotation of the feed-screws.

It is also desirable when the supplementary sliding bed, with the different operating-rolls, is raised or lowered into position that the mechanism for feeding the cake of coloring material be stopped from fu rther movement,or put into operation, respectively. In order to accomplish this result, the friction-disk Vis mounted upon a shaft W, Figs. 4, 5, and 11, which has a sliding as Well as a rotatable motion in its hearings. This shaft is held against the hub or boss a at one side by means of the spring w,which presses against acollarw', loosely surrounding the shaft, and which is prevented from rotating by means of the pin 10*, inserted into the main frame of the machine. This loose collar presses against a collar 10 rigidly secured to the shaft which forces a second collar-w on the shaft to force a loose earn-collar w against the hub or boss a. This cam-collar w has a cam or inclined surface w, Fig. 12, and a projection w", which enters into and engages theslot of a bifurcated shifting bar W, (see Figs. 5 and 11,) which has an inclined surface 20, that presses against the inclined surface of the loose collar w". As the operating-handle S is moved downwardly and inwardly the shifting bar is also moved inwardly to press against the cam-collar and force the shaft, with its friction-disk, inwardly and out of contact with the friction-wheel and at the time when the supplementary bed and operating-rolls are being raised from contact with the paper. A reverse movement of the operating-lever permits the engagement of the friction-disk and friction-wheel at the time when the operate ing rolls are being lowered into contact with the paper. The different rolls, shafts, and other mechanisms are operated by means of a main shaft Y, which is connected with all of the same by means of proper belts, as shown in Figs. 1 and 4. It is unnecessary and practically undesirable to letter or indicate these different belts and follow them by index-let ters, as it would only tend to obscure the drawings.
